Specification of Letters Patent.

Patented Oct. 17, 1905.

Application filed January 17, 1905. Serial No. 241,431.

To (all whom it may concern:

Be it known that I, HowARn K. KING, a citizen of the United States,residin at Philadelphia, in the county of Philade phia and State ofPennsylvania, have invented a new and useful Punching Mechanism forFolding- Machines, of which the following is a specification.

My invention relates to a punching mechanism to be operated inconnection with folding-machines.

The object of my invention is to afiiord simple, convenient, andefficient means for punching holes through separate signatures as thesame pass through the folding-machine, my device being adapted to makethese holes with such precision as to the lo cation of same that thehole in each signature when folded will register with the hole in everyother signature when a number of said signatures are assembled and soaccurately that the holes made in a number of signatures by one machinewill register with the holes of a number of signatures operated upon byanother machine, so that when a large number of said signatures arebound together into a single volume the said holes will all register, soas to form a continuous aperture through the corner of the entire volumefor the insertion of a string or Wire forming a loop whereby to hang thevolume. Such a device is especially useful in connection with thefolding and binding of bulky books which it is desired to hang in a convenient place for constant reference*-such, for example, as directories.

I accomplish my object by the mechanism illustrated in the accompanyingdrawings, in which Figure 1 is a plan view of a section of an ordinaryfolding-machine. Fig. 2 is a vertical section on line 2 2 of Fig. 1.Fig. 3 is a horizontal section, enlarged, on the plane indicated by theline 3 3 of Fig. 4. Fig. 4 is a vertical section on the plane indicatedby the dotted line 4 4 of Fig. 3. Fig. 5 is a vertical section on line 55 of Fig. 2.. Fig. 6 is a ver tical section on the plane indicated bythe dotted lines 6 6 in Fig. 5.

Similar numerals refer to similar parts throughout the several views.

As above stated, Fig. 1 is a plan view of a portion of an ordinaryfolding-machine of the same general type as those referred to anddescribed in patents, to me No. 667,021, dated January 29, 1901, and No.667,022, dated January 29, 1901. Reference being made to thedescriptions of folding-machines contained in said patents, a furtherdiscussion of the details of the folding machine is thought to beunnecessary in this connection.

Referring to Fig. l, the rollers 2 and 3 represent the ordinary foldingrollers of the folding-machine, which give the signature its last foldand from which rollers the folded signature is usually dropped into thepacking-trough 4.

Where it is desirable to provide a hole or perforation through thecornerof the completed volume, which is made up of a number of saidsignatures, I provide means for puncturing each signature, for example,as the same leaves the last folding-rollers 2 and 3 on its way to thepacking-trough 4. For this purpose I provide the rollers 5 and 6, gearedtogether and connected with the gear of roller 3 through theidler-pinion 7, so that said rollers 5 and 6 have a positive rotative'relation with the rollers 2 and 3, which are geared together at theirother ends by the pinions 8 and 9, respectively.

The rollers 5 and 6 have such a circumfere ential dimension as willinsure the passage of the signature through or between the same with onerevolution thereof. In. roller 5 is inserted the punch 11, while inroller 6 is inserted a cooperating die 12, these being so located on therollers with respect to the sig- .nature carried between them that thesaid punch will operate upon the signature 13 in one corner thereof andpunch the hole or aperture 14 in said signature 13, as shown in Fig. 5.The said members 11 and 12 are secured in their respective recesses inthe rollers 5 and 6 by the set-screws 15 and 16, respectively. (See Fig.3.) The roller 6 is also provided with a conical-shaped recess 17,concentric with its axis and surrounding the shaft 18, upon which saidroller is supported and. rotates. This recess 17 extends into the roller6 sufficiently in depth to connect with the aperture 19 at the rear ofthe die member 12, so that the punchings may be carried away from thedie member through said apertures 19 and 17. Against the apertured endof roller 6 is fitted the open end of conductor 20 for receiving andcarrying away said punchings. A deflector 21 may be secured to thisconductor 20, so as to project into the aperture 17 and which beingstationary will act as a plow or deflector to prevent the clogging ofthe punchings in said aperture 17.. This deflector is preferablyinclined to the plane passing through the axis of rotation of the roller6 for the purpose of increasing its efficiency in deflecting thepunchings into said conductor 20.

In the o eration of my improved means it is extreme y important that thesignature is not permitted to slip in its travel throu h said rollers 5and 6, since such slipping won (1 cause an error in the position of theaperture punched thereby, so that the same would not register with theapertures in other signatures. By the improvements above described I amable to secure an accurate adjustment of the various parts to secure thedesired accuracy in position of punching, and by this means of punchingone signature at a time it is possible to produce a volume of unlimitedbulk provided with the desired hole after the same has been assembledand bound. The punching mechanism above described is readily adapted tobe secured to the ordinary or standard folder and consumes absolutely noadditional time in its operation.

As a specific example of the manner in which my invention may be workedI have shown the punching-rollers as working in connection with therollers giving the last fold to the signature and so that the signatureshall be punched after receiving its last fold. It is obvious, however,that without departing from the spirit of my invention this punchingmechanism may be-differently located. For example, it may be located tooperate upon the signature before it receives its last fold, in whichcase it would only be necessary to provide the punching-rollers with twopunches and dies or to so reduce the circumference of the rollers thatthe punch would operate twice upon the signature passing therebetween insuch manner that when the signature has received its last fold theperforations therein will all register.

- l n like manner by keeping in mind the requirement that theperforations of the signature must all register in forming a single ingthe essential features of my invention may be located in differentplaces and operated in connection with different mechan-v isms of afolding-machine.

While .I have shown a rotary punching mechanism as the specific meansfor punching the signatures, other punching mechanism may obviously beemployed with similar result.

My invention, broadly stated, comprises mechanism operating inconnection with a folding-machine for punching one or more apertures ineach signature as the same passes through said folding-machine.

What I claim is 1. In combination with a machine for fo1ding signaturesheets, comprising foldingrollers and a reciprocating blade for strikingthe sheets between said rollers, a punching mechanism having suchoperative relationship with the folding-machine as to punch a holethrough each separate signature as it passes through the folding-machineso that the holes in all the signatures will register.

2. In combination with a machine for folding printed sheets comprisingfolding-rollers and a reciprocating blade for striking the sheetsbetween said rollers, punching mechanism comprising a second set ofrollers provided with punch and die, and geared with the folding-rollersand so positioned as to receive the folded sheets or signatures from thefolding-rollers to punch a hole in each signature so that the holes in anumber'of signatures when bound together, will register.

3. In combination with a folding-machine, comprising a pair offolding-rollers, a pair of additional rollers having a geared relationship therewith and provided with a punch and die'for operating upon thesignature carried therethrough, the die-roller provided with anaperture, communicating with the die, for receiving the punchings,conducting means, leading from said, aperture, for carrying thepunchings therefrom and a deflector for delivering the punchings fromthe roller to said conducting means.
